an expression for someone who overuses
his vehicle's horn, specifically holding it down for more than a second at a time.
a horn happy person is usually
on the road, and doesn't understand that
holding down a vehicle's horn is an aggressive action that
causes physical discomfort and harm
to people (pedestrians, cyclists and rollerbladers) in the immediate vicinity
of the car, in addition to irritating people who live in the area.
horn happy people are usually
unaware of just
how little actual value is added by their hooting - a typical result
of a lengthy hoot is the slowing
down or stopping of the person in front to see what all the trouble is.
